Summary :
Introduction: Hyposmia is a common cause of functional complaint in patients with nasal polyposis. The aim of the current study was to report the olfactory functional results after sinus surgery. Materials and methods: A systematic review of the scientific literature was achieved in the Pubmed database. Results: Overall, 10 series published between 1989 and 2013, involving 959 patients, were selected. The surgery for nasal polyposis, adjuvant medical treatment, may allow olfactory impro­ve­ment. The results are even better than surgery is as wide as possible and the evolutionary stage is low.
